To all whom it may com-em: V

lie'lt known that l, LA Vnnun -W. Norms,

,a citizen of the United States, residing at;

Chicago, in the county of Cook and State of Illinois, have invented it eertirin new and useful Improvement in Pulleys, of which the ollmving iso full, clear, concise, and exact. description, reference beinghad to the zu'com 'mnying drzuvings, -foru'iing 21. part of U this specification.

My invention relutes to pulley structures and has for its object the provision of an improved construction whereby pulley rims nniy be secured to pulley rim mountings without the intervention. of pulley spokes.

Generally speaking my invention resit in :1 pulley rim {ind a pulley rim mounting carrying pulley .rim fastening members provided with hook portions in engagement. with said pulley rim.

1n the preferred embodiment of my invention the pulley rim is provided with a. dished anchoring flange while the fastening meml'icrs are provided with; hooked or re turned ends that enter the dish of the flange to hold the flange in engugen'ient with the pulley rim mounting. Clamping means uredesirably employed for removuhly securing the fastening members in place upon the pulley rim mounting. The clamping means are desirably in the form of nuts that en; gage threaded extensions of the hooked portions, which. threaded extensions puss through the pulley rim mounting.

I will explain myinvention more fully by reference to the accompanying druvving showing the preferred embodiment thereof and in which Figure l is :1 view in sectional elevation on line 1 1 of Fig. 2; 2 is a view in cross section on line 2 2 of Fig. 1; and Fig. 3- is n detail sectional View.

Like parts are indicated by similar characters of reference throughout the different figures.

"The pulley rim mounting illustrated is in the form of the fly wheel a of on internal combustion engine, though I do not limit myself to the use of a Fly wheel us a mounting for the pulley rim. The wheel a. is pro vided With spokes b that radiate from the heel center. A seri s of nnnnlarly-dis posed cavities c extei through the Wheel spokes, the cavities in'euch ennuler set being equidistant from the axis ofthe wheel.

Patented Get. 17, lull.

llolt apertures (Z extend through the. spokes" in directions puruilel to the 213218 of i'Ottli-lO'll of the Wheel. By reason of Lire plurality of sets of unm'ilurly "llsposed cavities 0 the wheel a. adopted to hold pulley rims of ditlorent diunwters in position, a pulley rim e of one size being illustrated in position. This pulley rim is provided with at least one d shed anchoring flange f which is desirably eireumi'erentially eontin' ous and which is received within one setof ennulzirly disposed cnvities o. l usteningmem hers carried by the wheel, these t'zrstening n'iembers desirably residing in bolts hev ing threuded stems g und'chimping nuts h. The parts of the bolts opposite the ends engoged by the nuts h are provided with hooked or returned ends i that are received within the dish of the flange ,1, the anchoring flange being curled so that the returned ends or portion 2' oi ouch fastening member is received Within the cavity so that the rim proper is'upen one side of each portion 1'. and the tree. side of the hinge is upon an opposite side of each portion '5. lly tighteir ing the nuts 17! the [hinge portion of the pulley rim securely chnuped between the hooks 2'- und the (hinge seats formed by the cavities (a. l. do not wish to be limited to theclal'l'lplug nuts llv nor to the dished hinge upon the pulley rim, since the most iinpmtmit. feature' of? my invention resides in the i nsteir ing members hnvinghooluzd portions 1'. The embodiment ct the invention illustrated, however, is preterred since the pulley rims may readily be interchiingml and nmy rendily be replaced by pulleys of dillerentsizes, one pulley rim mounting thus being uduptable to pulley rims of varying dhuneters.

Having thus described my invention, 1. claim us new :uud desire to secure by Letters Patent the i llowing:

'l. A pulley rim provided with u curled anchoring hinge that n'tl'ords :1 cavity for the reception otiustenir members, in combiuution with a pulley rim mounting, to

toning members carried by the. pulley rim anchoring flange that afiords a cavity for the reception of fastening members, 111 c0111- bination with a pulley rim mounting, and festening members carried by the pulley IlIIl mounting and which fastening members are provided with returned portions received within said cavity in position to I havethe rim proper of the pulley upon one side of each of the returned portions and the free side of the flange upon an opposite side of each of the returned port-ions. 5

In Witness whereof, I hereunto subscribe my name this 15th day of April A. D., 1911.
